TRUCK/ Specification of Iletters Patent.

Patented Mar. 14, 1911.

Application filed November 8, 1910. Serial No. 591,252.

To all whom it may concern: Be it known that I, JOHN J. LABER, a cit-1- zen of the United States, residing at Harrisburg, in the county of Saline and State of Illinois, have invented certain new and useful Improvements in Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in trucks and more particularly to that class adapted to be used for transporting machinery in mines and elsewhere and my object is to provide a truck which may be readily moved over a trackway.

A further object is to provide a tilting portion, one edge of which may be lowered into engagement with a trackway when the machinery is being placed upon or removed from the truck.

A further object is to provide manually operated means for drawing the machinery onto the platform of the truck,'a'nd, a further object is to provide meansfor holding the platform against tilting when desired.

Other objects and advantages will be hereinafter set forth and pointed out in the specification.

In the accompanying drawings, which are made a part of this application, Figure 1 is a side elevation of the, truck, showing the tilted position of the platform by dotted lines. Fig. 2 is a longitudinal sectional view as seen on line 22, Fig. 3, and, Fig. 3 is a top plan view of the truck.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a frame, which is preferably rectangular in general outline and is suitably braced by means of cross bars 2, one end of the side rails of the frame being curved, as shown at 8 in Fig. 1. The frame 1 is mounted upon axles 4: and 5 and on said axles are securedwheels 6, which travel over the track rails 7, said wheels and track rails being constructed in the usual or any preferred manner.

Pivotally mounted on the axle 5 is a platform 8, said platform comprising a body portion 9 and arms 10 extending therefrom, said arms being preferably formed integral with the body portion. The arms 10 when in a horizontal position rest in ways 11 in the side rails of the frame, thereby securely bracing the platform when in a horizontal position. The platform is held against ti'lting movement by a keeper 12, which is slid a I ably mounted upon the frame 1 and has one of its ends projecting over the end of one of the side arms, the keeper being held in posit-ion on the frame by forming a slot 13 in one end thereof, which cooperates with a pin 14: carried by the frame. The under face of the forward portion of the platform 8 is tapered, as shown at 15, to bring said forward edge to a point so that when the platform is tilted the machinery or other devices will readily travel onto the platform. As the machinery to be transported is usually provided with wheels, the upper faces of the arms and the platform are provided with grooves 16 for the reception of said wheels, or if preferred, trackways may be placed thereon.

The side rails of the frame 1 are provided with guard rails 17 and the platform 8 is likewise provided with guard rails 18, which aline with guard rails 17 when the platform is elevated or in a horizontal position, thereby forming a continuous guard rail. The guard rails 18 project over the curved portion of theside rails of the frame and have a portion of their under faces curved, as shown at 19, which curved portion rests upon the curved ends of the side rails when the platform is lowered, thus strengthening the platform when the machinery is being placed thereon or removed therefrom.

In placing the machinery on the platform the keeper 12 is moved outwardly its full distance when the platform 8 will immediately swing on the axle 5 and the tapered end thereof engage the track rails 7. One end of a chain 20 is then engaged with the machinery when by rotating the sprocket wheel 21, with which the chain cooperates, the machinery will be drawn on to the plat form and as the machinery moves onto the platform it will be gradually raised to a horizontal position, where it is held by means of the keeper 12. The sprocket wheel 21 is mounted on a shaft 22, which is in turn mounted in bearings 23 on the cross bar of the frame 1 and said shaft is also provided with a ratchet 24, with which cooperates a pawl 25 of a swinging lever 26, which lever is pivoted on said shaft. The ratchet 24 is held against reverse rotation by means of a arm 29, which is substantially L-shaped and :and,git; will likewise be seen that latch 27, which is also mounted upon the frame 1. The free endof the lever 26 terminates in asocket in which is introduced one end of a bar 28, the major portion of said bar extending at an angle to the longitudinal trend of the lever. The chain 20 is held in proper alinement with respect to the sprocket wheel 21 by means of :a guide has one of its ends extended across the chain and sprocket, while the opposite end secured to the frame of the truck. The chain? alsotravels through. a loop30 on the-end of the. frame, said loop also serving to guide The ratchet and lever may also be used for easin g the;

the chain ronto the sprocket.

imachineryvoff thepIatform, in which i=n stance the latch 27 is disengaged from the; ratchet and the lever thrown over slowly? until it has reached it fullstroke, when by;

srengaging the ,latch with the ratchet the lever may be swung in the opposite direction to obtain a new purchase, :the aWl'being ifirst disengaged from the ratchet, Ethis;

operation being repeated until the maehinery is resting on the track rails.

" 'glhis device can be very cheap'ly icons; structed and at the same time rendered? extremely strong and durable and by :Prof providing the tilting iplatform it will :bef

seen that the machinery canbeeasily movedi upon the platform or vremoved 1th erefrom, 1 by @mounting the truck upon wheels, :as shown the machinery may be transported to any part; ofthe )mine or to any place outside of the mine where :a track is extended.

What I claim is:

1. A truck, comprising a frame, supporting axles therefor, -a"=platform having arms pivoted on one of said axles, the frame having ways therein in which said arms are embedded when in horizontal position and means to "hold the platform in a horizontal position. a

2. In a truck the combination with a platform, supporting "axles therefor and wheels .omsaid axles, of a platform having form, the guard rails (o th plat orm r fllng adapted to en "age the end of the ame when the plat rm is tilted the engag ng portion of said frame and guard rails be ng curved.
